Laboratorio de Inteligencia Computacional

Descripción

En el laboratorio de Inteligencia Computacional se realiza investigación en el área de reconocimiento de patrones usando técnicas de redes neuronales artificiales, computación evolutiva, big data, deep learning, machine learning y teoría de información.

Se desarrollan por una parte nuevos algoritmos y métodos (teoría) y, por otra parte, se aplican las técnicas de inteligencia computacional al procesamiento de imágenes y señales astronómicas, procesamiento de señales biomédicas, procesamiento de series de tiempo, diseño óptimo de empaquetamiento de baterías, big data, y data mining.
